You probably know that frogs hop ( 双足跳 ). But did you know that there’s a small frog in the Pacific Northwest that bellyflops（肚子先着水）? It’s called a tailed frog.
Dr.Rick Essner, who has been studying tailed frogs for the past few years, says, “ I’ve looked at thousands of jumps and have never seen them land on their feet like other frogs.” Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump.
Essner forst noticed these frogs because of the way they swim. Other frogs kick both of their back legs at the same time. But when a tailed frog swims, it pushes first with one leg and then the other.
To try to find out why tailed frogs bellyflop, Essner and other scientists collected and filmed different kinds of frogs. They found that all of the frogs start their jumps the same way: they hold out their legs. The change comes in the landing. Tailed frogs can't move their back legs as quickly as other frogs do. Maybe they don’t need to. Tailed frogs live around water and quickly jump into the water to escape danger.
Early frogs developed around watery areas and could jump quickly into the water to escape danger. Scientists think those frogs blended in with (与…融合在一起) the green plants on the side of the rocky rivers, just like today’s tailed frogs. “Ｉwould guess that other animals would have problems detecting them, ” explains Essner. When other animals find those early frogs, the frogs could jump into the river. They didn’t need to continue hopping.
Tailed frogs and other kinds of frogs went their own ways about 200 million years ago. Tailed frogs stayed by rivers. Other kinds of frogs moved to places where new hopping skills allowed them to survive.

It is natural that young people are often uncomfortable when they are with their parents . They say their parents don’t understand them .They often think that their parents are out of touch with modern ways , that they are too serious(严肃) — too strict with their children and that they seldom give their children a free hand . It is true that parents often find it difficult to win their children’s trust(信任) and they often forget how they themselves felt when they were young .
For example , young people like to act on the spot without much thinking . It is one of their ways to show they have grown up and that they can face any difficult situation . However , older people worry more easily . Most of old people plan things ahead , at least in the back of their minds , and do not like their plans to be upset by something unexpected .
When you want your parents to let you do something , you will have better success if you ask before you really start doing it .
Young people often make their parents angry with their choices in clothes and in music . But they do not want to cause any trouble ; it is just that they feel cut off from the older people’s world , into which they have not yet been accepted . That’s why young people want to make a new culture of their own . And if their parents do not like their music or hairstyle or clothes or their ways of speech , this will make the young people very happy .
Sometimes you are so proud of yourself that you do not want your parents to say “yes” to what you do . All you want is to be left alone and do what you like . It is natural enough , after being a child for so many years , when you were completely under your parents’ control .
If you plan to control your life , you’d better win your parents over and try to get them to understand
you. If your parents see that you have a high sense of responsibility , they will certainly give you the right to do what you want to do .

Admit(承认) that you don’t know .You may tell them that you can’t remember someone’s name . Most of them will feel glad if you say, “I’m working to remember your names better . Yours is right on the tip of my tongue . What is it again?”
Use associations(联想). Link each person yon meet with one thing you find interesting or unusual．
For example, you can remember in this way : “Vicki Cheng ——tall, black hair.” To remember their names , you can write them on a small card as soon as possible.

October is usually a happy time for me ---- my grandchildren , Daniel and Carly , get all excited about Halloween . They often spend time dreaming of their activities and candies a few weeks .
More than anything else, though, they love best. But not just any pumpkins(南瓜). They wanted the ones by their great aunt Margret--- my sister. I to joke that she had a place in her backyard that attracted those kids deeply .That’s where the pumpkins grew. She and the kids the pumpkins, putting a wooden box under each one so it wouldn’t roll down to the ground. Whenever I took my grand children to visit Margaret, they would say hello to her before running into the to see what was going on there. They harvested (收割) them and used the ones for Halloween.
I didn’t know why or how pumpkins grew in such a place Margret had never planted seeds (种子) there before. Maybe she had just an old pumpkin out there. She was good at gardening, though. I hoped that I had been given Margret’s gardening.
What would my grandchildren do this first Halloween after my sister ? I wished there were some other ways to make the day so as to let Daniel and Carly know their great-aunt’s lived on.
Next day I went to the kids. Upon walking in, I was greeted by their quickest hello, “Grandma! Grandma! Come and see!”
“See what? ”
“ Just come!” they said, my hands and pulling me with them. We went outside. There, right on the side of the house, were six pumpkins, growing in a place where had ever been planted before.
I said, “You know what great- aunt Margret would do if she were here…” We all ran to the kitchen to get some . The big pumpkins were used for Halloween. Those left were used to beautify the front doorway. They lasted for and served as an autumn-long reminder for my two little pumpkin kids.
